One of the new features is the Command Palette (accessible via the Tools menu), which provides a keyboard driven way to select commands usually relegated to the menu - it's especially useful for switching the currently active syntax highlighting mode. It's driven by *.sublime-commands files, of which there's currently only one, in the Default package. It's fairly spartan; I'm more than happy to receive any patches here.

Also new in this build is the long awaited quick panel API, allowing plugins to present lists to the user. A short example that presents two items, each with 2 bits of secondary information to the user:

You make my day Jon !Quick panel look great and I like the new Command Palette very much, great idea !Is there a way to customize the content of the Command Palette using the Syntax Type of the active view (to have per file type command) ? Like context:selector ?
